Answer 1

You might want to consider adding two columns on you user info table. Something like varchar activation_code & tinyint activated. On save user info generate activation code and send user a mail with that code within a link of your application url as well as save that code for that specific user with activated false value. On verify that code using that link change activated to true.
That will be my approach.

Before we start, I just want to point out that you should not have queries in your controller. That part must be in a model.
To send an email, you can use the codeigniter's library :
https://ellislab.com/codeigniter/user-guide/libraries/email.html
Here's how you can use it in your case :
if($this->form_validation->run()==FALSE)
{
$this->load->view('form_view');
}
else
{
$email = $this->input->post('email');
//Your stuff before the redirect
//If you have any particular smtp configuration (here, gmail)
$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'smtp.gmail.com',
'smtp_user' => 'myemail#gmail.com',
'smtp_pass' => 'mypassword',
'smtp_port' => '465',
'charset' => 'utf-8',
'wordwrap' => TRUE
);
$this->load->library('email', $config);
$this->email->from('MyName#MySite.com', 'MyName');
$this->email->to($email);
$this->email->subject('Mail subject');
$msg = "Welcome to my website !";
$this->email->message($msg);
if($this->email->send())
{
//Stuff if mail succeded
}
else
{
//Stuff if mail failed
}
redirect('main/viewForm');
}
